statsmodels upgrade

[jabbera]

Describe the problem.
statsmodels < 13 can't be installed with scipy >= 1.8.0: https://stackoverflow.com/questions/71106940/cannot-import-name-centered-from-scipy-signal-signaltools

This is a valid configuration per this projects setup.py:

gs-quant/setup.py

Lines 76 to 77 in 1272790

	"scipy>=1.2.0,<=1.8.0;python_version>'3.6'",
	"statsmodels>=0.11.1,<0.13.0",

Repro:

python3 -m venv .venv
source .venv/bin/activate
pip install gs-quant
python -c "from statsmodels.api import OLS"

Traceback:

  from pandas import (to_datetime, Int64Index, DatetimeIndex, Period,

Describe the solution you'd like
Remove the requirement for statsmodels < 13. I really don't want to be pinned to scipy < 1.8.0

Describe alternatives you've considered
Downgrade scipy.

Are you willing to contribute
Need to check with my legal department.

Agree that this is an issue. Would be at least nice to know why the statsmodels version is capped

[S-Manglik]

Statsmodels is now unpinned and we are working on unpinning scipy.

@S-Manglik this change was rolled back here: https://github.com/goldmansachs/gs-quant/pull/253/files#diff-60f61ab7a8d1910d86d9fda2261620314edcae5894d5aaa236b821c7256badd7

was this intentional?
